This virtual manipulative is designed to teach the concept of a function by allowing you to experiment with various functions. This animation helps students to understand the function concept through the "machine" metaphor. The domain elements (input) are dragged into the machine, which then goes through some (unseen) process and spits out the range element corresponding to the input. The results are then displayed in tabular form.
Drag each number into the function machine and look for a pattern that will allow you to complete the table.
You can experiement with functions right on the Internet or download a free trial desktop version.

Have students pair to discover the simple functional relationship of specific patterns.

2.

Have each pair discuss different ways to verbalize the functional relationship, and perhaps to play with the idea of how far the domain might be extended.

"I founded SAV school to educate poor family children of the rural area of Nepal seeing some parents unwilling to educate their children and some parents willing to send their children to teach them english. I've been focusing my strategy to bring the poor children to school and educate them in English medium. Parents love to hear their children speaking English. English is our second language. I look forward to sharing and connecting in My eCoach
